You cannot use PHP in your templates in Smarty 4. So none of your options will work.

If you just wanted to echo "hello", you would just write "hello", but I suppose you want to do something else?

See https://smarty-php.github.io/smarty/getting-started.html for some basic usage examples.

tanX. "but I suppose you want to do something else?" answer:yes i want use php in tmplate for use of my objects together smarty protifs .but i think .parser smarty this important option that use php in template dont support .
(PHP will now be passed through as is.???). What does this phrase mean?for use embedded PHP in templates.
Anyway, thank you. And if there is a way to use php in smarty, please help. Thank you again for your answer.

Keep your PHP and your templates separate. That is what template engines like Smarty are for.
So: run all the PHP code you need to run, assign the results to a template variable and then display the template.

Taking the option away to use it is not good. You are trying to control the developer's choices. CSS is cached by the browser and the flykit mod allows people to design themes on the fly. It loads CSS in a PHP file bypassing the cache system for design purposes only. It is enabled with define("FLYKIT", true); and is only used to create themes. How would you suggest loading CSS as a PHP file with Smarty 4?
